Pavel Solodovnikov adc6a98b59 cql3: return raw::parsed_statement as unique_ptr
Change CQL parsing routine to return std::unique_ptr
instead of seastar::shared_ptr.

This can help reduce redundant shared_ptr copies even further.

Make some supplementary changes necessary for this transition:
 * Remove enabled_shared_from_this base class from the following
   classes: truncate_statement, authorization_statement,
   authentication_statement: these were previously constructing
   prepared_statement instance in `prepare` method using
   `shared_from_this`.
   Make `prepare` methods implementation of inheriting classes
   mirror implementation from other statements (i.e.
   create a shallow copy of the object when prepairing into
   `prepared_statement`; this could be further refactored
   to avoid copies as much as possible).
 * Remove unused fields in create_role_statement which led to
   error while using compiler-generated copy ctor (copying
   uninitialied bool values via ctor).
